Patented July 1930 JOHN w. JENKINS, or EMPORIA, KANSAS WALL CONSTRUCTION Application filed January 26, 1929. Serial No. 335,228.

My invention relates to a wall construction,

and the blocks forming the same.

In accordance with my invention, I provide a wall which is formed of layers of blocks. The blocks are provided at their opposite ends with horizontally projecting extensions or tongues, disposed at the opposite faces or sides of the block. WVhen assembled, the horizontal extensions of the blocks, in alternate layers, break joint, and also afford vertical passages within which concrete is poured.

The blocks are provided upon their tops andbottoms with grooves or channels, affording horizontal passages, 1n COInIIlLlIllCZttlOIl with 1 5 the vertical passages, also adapted for the reception of fluid concrete. \Vhen'the blocks are assembled in the wall, the concrete is "poured into the vertical passages, and runs into the horizontal passages, thereby providing vertical andhorizontal reinforcing con crete bars, which are integral with each other,

and secured to the blocks. A wall construction is also providechwhich is solid and substantially integral, thereby having the maximum strength. The adjacent edges of the blocksniay be slightly spaced, whereby the fluid concrete will from the inner side.

In the accompanying draw1ngs,,forming a pass between the blocks,

part of this specification, and in which like.

numerals are employed to designate like parts throughout the same,

Figure 1 is a side elevation of a section of a wall embodying my invention,

Figure 2 is a plan view ofthe same, Figure 3 is an end elevation of the same, Figure 4 is a central vertical section through a section of the wall, 7

Figure 5 is a perspective view of one of the blocks embodied in the wall,

Figure 6 is a plan view of the same, and Figure 7 is an end elevation of the same. Each block embodies a body portion 36,

formed of concrete or the like. This body H intothe vertical passages 41, and willpass portion is rectangular and has a greater height than width. The body portion is provided at each end with a longitudinally projecting extension or tongue 87, disposed flush with the outer surface of the body portion 36. The extension 37 at one end of the block is disposed at one side of the same,- and" the extension37 at-the opposite end of the block is disposed at the opposite side of the block. The body portion 36is provided in its top and bottom with longitudinal grooves 39, extending throughout the entire length of the same. These grooves are 1 substantially V- shaped in cross section and have inclined walls extending inwardly from points. adjacent to the longitudinal extensions to the centrallongitudinal axis of the body portion. 7 The substantially V-shaped grooves 39, when assembled with corresponding grooves inthe adjacent layers,prjodu'ce passages which are rectangular 'orsubstantially square in cross section, whereby the horizontal concrete col- 7 u'mns to be produced thereby are of a' similar shape in cross sectionand are adapted to have wedging action with the body portions of the blocks. Further, there are no, abrupt surfaces 76 of the blocks to engage with these. concrete columns and which would readily break; The blocks are, preferably formed of concrete or other plastic material. H1

The wall construction is shown in Figures 7 1 to 4, inclusive. In these Figures,the numere140 designates-a concrete footing, upon which the blocks are arranged in horizontal layers. The extensions or tongues 37 of the blocks in each successive horizontal layer are arranged to break joint with the extensions or tongues of theblocks in the adjacent layer. This is readily accomplished by reversing the blocks in the successive layers when I laying the same. If desired, the blocks may be retained slightly spaced when assembled, V

for a purpose tobe described. The arrangement of the blocks in the horizontal layers, as described, affords vertical passages 41, pro" duced by the extensions 37 and horizontal passages 42 produced by the grooves or channels 39, thesevertical and horizontal passages being in free communication. As clearly shown in Figure 4-, concrete 43 may be poured L), e3 downwardly therein andinto the horizontalv j passages 42,- thereby producing, integral ,v'ertical and horizontal reinforcing bars, which are securely bonded to the blocks; If, desired, reinforcing irons may be arranged.

within the passages. If the adjacent edges of the blocks are slightly spaced, some of the concrete will pass outwardly, between these edges, thus cementing the edges of the blocks together:

In the use of the molding apparatus, with the parts assembled, as shown in Figures 8 to 12, inclusive, the plastic material or concrete mix, may be readily poured into the top of the same, to properly fill the mold cavities. After the concrete has properly hardened, the sides 16 of the mold apparatus may be readily removed, and also the upper pallet 35, withdrawing the members 3d. The blocks may now be readily removed from the base 15 and may be arranged in a drying chamber to be suitably cured or seasoned. After the blocks have properly hardened, they are assembled into the wall, as described, and the vertical and horizontal passages between the same are filled with fluid or plastic concrete.

It is to be understood that the form of my invention, herewith shown and described, is to be taken as a preferred example of the same, and that various changes in the shape, size and. arrangement of parts, may be resorted to without departing from the spirit of my invention, orthe scope of the subjoined claim.

Having thus described my invention, I claim:

A wall construction, comprising a plurality of horizontal layers of concrete blocks, each block having a body portion of greater height than width, each block being provided at each end with one longitudinal extension which is flush with the outer surface of the body portion, the two extensions on each bloclr being arranged upon opposite sides of the body portion, said body portion having grooves in its top and bottom, said grooves being substantially V-shaped in cross section and having inwardly inclined walls which extend from points adjacent to the inner faces of said extensions to the center of the body portion, the longitudinal extensions in one layer being arranged to break joint with the extensions in the adjacent upper and lower layers, the ends of the body portions of the blocks in the several layers being in vertical alignment, the arrangement being such that said extensions -form continuous vertical passages'and the grooves continuous horizontal passages which are substantially square in cross section with their sides arranged obliqnely, and a concrete filling for the horizontal and vertical passages producing horizontal and vertical columns which are integral with each other, the horizontal columns being substantially square in cross section for wedgingaction with the walls 01 the horizontal passages. f 1

In testimony whereof I aflix my signature.
